Th'ecrOss-piece 20 isepertured, esrepregetherV With ythe Wire Wound thereon', ere located, the peripherel'swell of the housing L13 containing an openingglfi through which' LtheOuter end' of 'the Wire,` ongthelreel, eX- tends.- The constructionshownisedepted -l sented at 23, and the tube 17 is secured to this member' atsaid aperture. A desirable Way of securing these parts together, is toiorm the tube 17 with an upset portion 211 to form a flange betweenWhich and the oilset portion 25, at the rear extremity ot" the tube 17,the yoke bracket is securely held to the tube.

The device shown also comprises a jack, represented at 26, whichconnected with the'outer ends` ot the wires 8, which latter extendthrough the tubular member T17, this jack serving to control the ilov:ol current to the ignition device hereinafter referred to. The jackshown eoiuprises a casing, or shell, 27 preferably constructed oln anysuitable non-hezit-conducting material, the end Wall oi2 Whichapertured, as represented at 28, through which apertrue the wires S leadinto the interior oli the shell, the opposite end of the shell 27containing a threaded electrical sockel: 29 the outer threaded contactoi Which is represented at il() and the center contact ot which isrepresented at 31. One of the wires tv connects through a strip 32 ofcurrent-conducting material, With the outer contact BO, the strip 32being held in position by a screw 53 passing through the casing 27 andscrewing into this strip, and the other oit the Wires 8 connects with aspring contact strip ill supported at one end by, but out ot electricalcontact With, the contact strip 32, through the medium of a rivetthestrip-34 which extends directly above a resilient strip 36 ofcurrent-insulating material, likewise supported by the strip 32 at therivets 35, cooperates with the contact portion 37 ot' the center contact31, the parts being so constructed and arranged that when the lack 26 isremoved from the tubular mem er 17, in which it is located when thedevice is not in use, the contact strip 3ft will be in engagement withthe Contact portion 37 as shown in Fig. el, whereby the circuit throughthe jack is closed. The means provided in the particular' constructionshown for automatically breaking the circuit through the jack when thelatter is inserted into the supporting tube 17, and causing the circuitto become re-established upon withdrawing the jack from the support,coniprises abutton 38 which is located, and longitudinally movable, inan opening 3.() in a side Wall of the casino4 27, the inner end of thisbutton being connected with the contact 34. The parts are soproportioned that When the contact etis in engagement with the contactportion 37 the button 38 projects laterally beyond the outer surface ofthe casing 27 and is forced inwardly to a position in which the contact3e disengages from the contact portion 37, by the engagement of thebutton With the inner surface of the tube 17, upon introducing it intothe latter The :tree end otto the position shown in Fig. l, the contact34 automatically engaging with the contact portion 37, upon theWithdrawal ot' the jack 'from the tube 17. The jack 2b is adapted toreceive any suitable device to be energized, as, for exan'iple, thecigar-lighting elementI represented generally at 4l) and illustrated indetail in Fig. 5. The particular ignitingl device shown comprises ametal shell lll formed at one end with the reduced threaded portion Ll2adapted to screw into the threaded contact 3() oi the jack, the oppositeend ol this shell being open as riuiresented. The shell Ll-l contains abody lil olE any suitable current-insulating material and the ciechi calheating elenient shown as in the torni of a coil and represented at 4st,one end ol this coil being connected with the shell Ll-1, as representedat 45, and the other end thereof` represented at 46, connected with ascrev.' i7 which is insulated from the shell lli by the interposedmaterial 4B, the contact 117 cooperating with the center contact 3l o'l'the jack. rlhe heating coil fl-lf in shown as in-` terposed betweendisks 418, Lil-9 and 5t) preteraloly of mica and provided in accordancewith common practice, the disks at) and 5() containing registeringopenings therein permitting ol access to the coil 44 for the lighring ofa cigar. The device. Ll() also comprises a band 5l oibeat-non-conducting material which surrounds the shell il and adapcs thedevice to be handled by the operator Without danger ot' burning hislingers. Then the device l0 is assembled With the jack 26 these partsvirtually form a unitary structure which is adapted to be Withdrawn fromthe tube 17 to the desired point ot use, the Wires 8 unwinding from thereel 9 in this operation, it being understood that upon removing thejack 26, as stated` the circuit is immediately established through thejack.

lt will be noted from the'foregoing that inasmuch as the heating element410 is lsurrounded by the member 51 ot iioii-heatco1i ducting material,danger of the burning o the fingers of the operator, in grasping thispart of the device, is prevented, Ait is not necessary that any more otthe device than the part just referred to be exposed at the front sideof the board 15, and thus the de vice is rendered very inconspicuous.

lllhile I have illustrated and described a particular constructionembodying my invention, I do not u'ishjto be understood as intending tolimit it thereto as the same may be variously modified and alteredwithout departing 'from the spirit ol' my invention,

Vilhat I claim as new, and desire to secure by Letters Patent, is:

l. ln a device of the character l'ortll, the combination of a trame, aspring-actin ated reel mounted therein, a stationary tubularguide-member, a jack comprising a tubular jack-casing adapted to besheathed in saidtubular I guide-member and provided with a lateralperforation, a` movable circuit-closer mounted in said jack-casing, a

contact in said jack-casing automatically en gaged by saidcircuit-closer ywhen theJack-v casing is Withdrawn fromthe tubularguidemember, and a button projectingrthrough the lateral perforation ofthe jack-casing and adapted to bejactuated `by said tubular guide-memberto, break the circuit in the operation of sheathing the jack-casing, and

an electric cord connected with said reel and serving to draw saidjackinto its sheathed position and cause the circuit to be automaticallyvbroken thereby.

n 2. In a device ofy the character set "forth,

"fthe combination of a frame, a spring-actuated reelmounted therein, afixedly' mounted tubular guide-member upon which said frame isvmountedand carried, la ,jack coml prising a tubularfjack-casing adaptedto be sheathed in said tubular 'guide-member andA provided with alateral perforation, terminals for said jack, a contact -member con.-nected `with one of said terminals, andy a ycircu1t-closer mounted 1nsaid Jack-cas1ng `andadapted to vengage said contact, ,said

circuit-closer having` secured thereto, a later-y ally vprojectingbutton"` extending., freely .through said perforation,v and an 4electric cord connected with f said tubular `guidemember, saidcordfbeing extendedinto and secured to said jack-casingv and having oneconductor electrically connected with said circuit-closer *andy anotherconductor electrically connected with the other terminal of the jack,said vcircuit-closer serving' to. automatically close the circuit whenthejack-casing `is Withdrawn from the guide.

the combination ofartubular guide-member adapted `to servey as a sheathfor a jack, means for `clampingly securing said member in a perforationlin a support, said means including a nut screwed upon` the front end ofsaid member and having an internal y.langeabutting against the lend ofsaid tubular member, the wall of the opening through said nut beingrounded and outwardly ilaring, in combination with a jack comprising atubular member adapted to be sheathed in said guide-member, and acircuit-closer in said second named tubular member equipped withaqlaterally projecting button adapted to be forced inwardly by theguide-member to automatically break the circuit in the operation of'rsheathing theA jackv insaid guide-member.
